Referring to fig. 3, an embodiment of the present disclosure provides an air conditioner including an indoor unit and an outdoor unit. The indoor unit includes an indoor heat exchanger 503, the outdoor unit includes an outdoor heat exchanger 504 and a compressor 501, and the compressor 501, the indoor heat exchanger 503 and the outdoor heat exchanger 504 are connected in sequence by a pipe 507 to constitute a main part of the refrigerant circulation flow path 50. For example, the air conditioner further includes a four-way valve through which the refrigerant flowing out of the compressor 501 flows to the indoor heat exchanger 503 or the outdoor heat exchanger 504, and the four-way valve also belongs to a part of the refrigerant circulation flow path 50.

The refrigerant circulates in the refrigerant circulation flow path 50 to realize the normal operation of the air conditioner. The refrigerant flowing out of the compressor 501 enters the indoor heat exchanger 503 or the outdoor heat exchanger 504 first to distinguish between heating and cooling.

The air conditioner further includes a first magnetic attraction member 20 and a variable magnetic field.

As shown in fig. 1, 2 and 6, the first magnetic member 20 is disposed in the refrigerant circulation passage 50.

The first magnetic member 20 may be disposed in a part of a pipe line in the longitudinal direction (the refrigerant flowing direction) of the refrigerant circulation flow path 50, for example, between the indoor heat exchanger 503 and the outdoor heat exchanger 504, or may be disposed along the longitudinal direction (the refrigerant flowing direction or the opposite direction) of the entire refrigerant circulation flow path 50. When the refrigerant circulation path 50 is provided along the longitudinal direction of the entire refrigerant circulation path 50, the refrigerant circulation path may be uniformly provided along the longitudinal direction of the entire refrigerant circulation path 50, or may be non-uniformly provided, for example, when the refrigerant circulation path is non-uniformly provided, the refrigerant circulation path may be provided with a large amount in the pipe 507 and a small amount in the compressor 501, the indoor heat exchanger 503, and the outdoor heat exchanger 504, or may be provided with a small amount in the pipe 507 and a large amount in the compressor 501, the indoor heat exchanger 503, and the outdoor heat exchanger 504.

The variable magnetic field corresponds to the first magnetic attraction piece 20 and a magnetic field force which is variable along the extending direction of the refrigerant circulation flow path 50 where the first magnetic attraction piece 20 is located exists between the variable magnetic field and the first magnetic attraction piece 20.

The magnetic force along the extending direction (length direction, flowing direction of the refrigerant or the opposite direction) of the refrigerant circulation flow path 50 where the first magnetic attraction member 20 is located refers to the entire magnetic force along the extending direction of the refrigerant circulation flow path 50 where the first magnetic attraction member 20 is located, or the magnetic force may have a component along the extending direction of the refrigerant circulation flow path 50 where the first magnetic attraction member 20 is located. As shown in fig. 1 and fig. 2, the direction of the entire magnetic field is along the extending direction of the refrigerant circulation flow path 50 where the first magnetic attraction member 20 is located; as shown in fig. 3, the magnetic force has a component along the extension direction of the refrigerant circulation flow path 50 where the first magnetic attraction member 20 is located.

Regardless of whether the magnetic force is along the extending direction of the refrigerant circulation flow path 50 where the first magnetic attraction member 20 is located, or the magnetic force has a component along the extending direction of the refrigerant circulation flow path 50 where the first magnetic attraction member 20 is located, the magnetic force has a driving force for driving the first magnetic attraction member 20 to flow along the extending direction of the refrigerant circulation flow path 50 where the first magnetic attraction member 20 is located.

Changing the magnetic force, including changing the magnitude and/or direction of the magnetic force, can correspondingly change the magnitude and/or direction of the driving force, and thus correspondingly change the speed and/or direction of movement of the first magnetic attracting element 20.

When the moving direction of the first magnetic attraction piece 20 is consistent with the flowing direction of the refrigerant at the position of the first magnetic attraction piece 20 and the moving speed of the first magnetic attraction piece 20 is greater than the flow speed of the refrigerant, the first magnetic attraction piece 20 can increase the flowing speed of the refrigerant; when the moving direction of the first magnetic attraction piece 20 is consistent with the flowing direction of the refrigerant at the position of the first magnetic attraction piece 20 and the moving speed of the first magnetic attraction piece 20 is less than the flow speed of the refrigerant, the first magnetic attraction piece 20 can reduce the flowing speed of the refrigerant; when the moving direction of the first magnetic attraction piece 20 is opposite to the flowing direction of the refrigerant at the position of the first magnetic attraction piece 20, the first magnetic attraction piece 20 can reduce the flowing speed of the refrigerant.

The flow velocity of the refrigerant can be changed by changing the moving direction and/or speed of the first magnetic attraction piece 20, so that the stepless regulation of the flow velocity of the refrigerant is realized. The change of the flow velocity of the refrigerant can effectively improve the effect in the refrigeration and heating, and accelerate the process of temperature reduction and temperature rise.

Optionally, the variable magnetic field includes an energizing solenoid 10, the energizing solenoid 10 is sleeved outside the refrigerant circulation flow path 50, and the energizing condition of the energizing solenoid 10 is changed to change the magnetic force of the energizing solenoid 10 on the first magnetic attraction piece 20. Wherein, the energizing condition includes at least one of on/off, direction of current and magnitude of current when energized, and changing the magnetic force of the energized solenoid 10 on the first magnetic attracting member 20 includes changing the magnitude and/or direction of the magnetic force.

As shown in fig. 1, the direction of the current I in the energized solenoid is indicated by an arrow at I, and a magnetic field is formed in the refrigerant circulation flow path from the S pole to the N pole. As shown in fig. 2, the direction of the current I in the energized solenoid is indicated by an arrow at I, and a magnetic field is formed in the refrigerant circulation flow path from the S pole to the N pole. The direction of the current in the energized solenoid of fig. 1 and 2 is opposite, and thus the direction of the magnetic force on the first magnetically attractive element is opposite.

The energizing solenoid 10 includes a helical energizing coil which is fitted around the outside of the refrigerant circulation passage 50.

The air conditioner further comprises a controller connected to the energized solenoid 10 for controlling at least one of the power-on/off, the current direction when energized, and the current magnitude of the energized solenoid 10, so as to change the magnetic force of the energized solenoid 10 on the first magnetic attraction member 20.

The controller may determine a flow rate requirement of the refrigerant according to an operation mode of the air conditioner, an indoor/outdoor environment parameter, and the like, so as to control at least one of power on/off of the energized solenoid 10, a current direction when energized, and a current magnitude, wherein the indoor/outdoor environment parameter includes an indoor/outdoor environment temperature and/or humidity.

In one embodiment, when the air conditioner operates in the heating mode, the controller controls the energizing solenoid 10 to be energized, and the magnitude and the direction of the current in the energizing solenoid 10 are such that the direction of the magnetic field force of the energizing solenoid 10 on the first magnetic attraction member 20 is the same as the flowing direction of the refrigerant in the refrigerant circulation flow path 50 at the position of the first magnetic attraction member 20, and the moving speed of the first magnetic attraction member 20 is greater than the flow path of the refrigerant, so that the first magnetic attraction member 20 increases the flow rate of the refrigerant.

When the air conditioner operates in a cooling mode, the controller controls the energization solenoid 10 to be energized, and the current magnitude and direction in the energization solenoid 10 are such that the direction of the magnetic field force of the energization solenoid 10 to the first magnetic attraction piece 20 is the same as the flow direction of the refrigerant in the refrigerant circulation flow path 50 at the position of the first magnetic attraction piece 20, the movement speed of the first magnetic attraction piece 20 is smaller than the flow path of the refrigerant, or the direction of the magnetic field force is opposite to the flow direction of the refrigerant in the refrigerant circulation flow path 50 at the position of the first magnetic attraction piece 20, so that the first magnetic attraction piece 20 reduces the flow rate of the refrigerant.

Optionally, the variable magnetic field further includes an iron core, the iron core is fixedly disposed in the refrigerant circulation flow path 50, and the energized solenoid 10 is sleeved outside the iron core to enhance the magnetic field generated by the energized solenoid 10.

Alternatively, the core is located at the position of the axis of the refrigerant circulation flow path 50 and extends along the axis. The distances from the respective refrigerant circulation passages 50 at the circumferential positions of the energized solenoid 10 are equal to each other, in other words, the refrigerant circulation passages 50 are located in the axial direction of the energized solenoid 10.

Optionally, the refrigerant circulation flow path 50 includes a sleeving section 505, the first magnetic element 20 is located in the sleeving section 505, and the corresponding energized solenoid 10 is sleeved outside the sleeving section 505.

The refrigerant cycle includes a compressor 501, a four-way valve, an indoor heat exchanger 503, an outdoor heat exchanger 504, and other devices, and a pipeline 507 connecting these devices, and the sleeving section 505 may include at least a part of the pipeline 507 and/or at least a part of the devices, for example, the sleeving section includes a part of the pipeline 507 in fig. 1 and 2. In other words, the energized solenoid 10 may be disposed over the conduit 507, or over the device, or partially over the conduit 507, or partially over the device.

The sleeving section 505 is linear, so that the magnetic force generated by the energized solenoid 10 to the first magnetic attraction member 20 extends along the sleeving section 505, in other words, the magnetic force extends along a straight line, and the first magnetic attraction member 20 flows along a straight line, thereby preventing the first magnetic attraction member 20 from flowing along a direction deviating from the straight line to cause the first magnetic attraction member 20 to be attached to the inner pipe wall of the sleeving section 505.

Optionally, there is no magnetic field force between the sleeved section 505 and the variable magnetic field. The sleeve section 505 may be made of a non-magnetic material, such as a non-fe-co-ni material.

Optionally, the air conditioner further includes a protective layer, the protective layer is disposed on an outer side of the refrigerant circulation flow path 50, and the energized solenoid 10 is disposed on an outer side of the protective layer.

The protective layer is sleeved outside the sleeved section 505, so that the sleeved section 505 can be protected, and the service life of the sleeved section 505 is prolonged. The protective layer is made of nonmagnetic material.

Optionally, as shown in fig. 4 and 5, the variable magnetic field comprises a second magnetically attractive element 30 and a third magnetically attractive element 40.

The second magnetic attraction piece 30 and the third magnetic attraction piece 40 are sequentially arranged along the extending direction of the refrigerant circulation flow path 50 where the first magnetic attraction piece 20 is located, the second magnetic attraction piece 30 and the third magnetic attraction piece 40 can attract each other, and one of the second magnetic attraction piece 30 and the third magnetic attraction piece 40 forms an N pole and the other forms an S pole. As shown in fig. 3 and 4, the second magnetic member and the third magnetic member may be located on the same side of the axis of the sleeving section, or on two opposite sides of the axis.

The first magnetic element 20 is located in the magnetic field formed by the second magnetic element 30 and the third magnetic element 40, and receives a magnetic force along the extending direction of the refrigerant circulation flow path 50 at the position of the first magnetic element 20.

The second magnetic element 30 can move relative to the third magnetic element 40, for example, move relatively along the length direction of the cooling medium circulation flow path 50 at the position of the first magnetic element 20, or move relatively along the length direction of the cooling medium circulation flow path 50 at the position offset from the position of the first magnetic element 20. After the second magnetic element 30 moves relative to the third magnetic element 40, the magnitude and/or direction of the attraction between the second magnetic element 30 and the third magnetic element 40 changes, so that the magnetic force of the second magnetic element 30 and the third magnetic element 40 on the first magnetic element 20 changes, and the flow rate of the refrigerant can be changed.

The second magnetic element 30 and the third magnetic element 40 can be both electromagnets, or one of them can be an electromagnet and the other can be a permanent magnet.

The change of the magnetic force of the variable magnetic field received by the first magnetic element 20 can be realized by the relative movement of the second magnetic element 30 and the third magnetic element 40, or can be realized without the relative movement. For example, when the second magnetic attracting element 30 and/or the third magnetic attracting element 40 are electromagnets, the magnetic force of the variable magnetic field received by the first magnetic attracting element 20 can be changed by changing the energization condition, the energization direction and/or the magnitude of the current of the electromagnets.

Alternatively, as shown in fig. 1 and 2, the number of the first magnetic attracting elements 20 is a discrete plurality.

The number of the first magnetic attracting elements 20 is plural, and the plural first magnetic attracting elements 20 are independent and have no connection relation with each other. Thus, the plurality of first magnetic attraction pieces 20 can be distributed at different positions of the refrigerant circulation flow path 50, so that the flow speed of the refrigerant at different positions can be adjusted, the flow speed of the refrigerant is uniformly improved, and the refrigerant in the whole refrigerant circulation flow path 50 flows smoothly and stably.

The number of the first magnetic attraction pieces 20 can be reasonably selected according to the inner diameter of the pipeline 507 in the refrigerant circulation flow path 50 and the requirement on the cooling and heating efficacy of the air conditioner. For example, the larger the inner diameter of the conduit 507, the greater the number of first magnetic elements 20.

The size of the first magnetic member 20 needs to be smaller than the minimum size of the refrigerant circulation flow path 50 on the flow path of the first magnetic member 20, so as to prevent the first magnetic member 20 from being blocked by the refrigerant circulation flow path 50 and being unable to flow.

Optionally, the first magnetic attraction member 20 includes a magnet, which may be made of iron, cobalt, or nickel, so that the first magnetic attraction member 20 can be acted by a magnetic force when being located in a magnetic field.

Optionally, the refrigerant circulation flow path 50 includes an indoor heat exchanger 503, an outdoor heat exchanger 504, a compressor 501 and a connection pipe 506, and it can be understood that the pipeline includes the connection pipe 506, and the connection pipe 506 includes a sleeve section. One end of the indoor heat exchanger 503 is connected to the compressor 501, one end of the outdoor heat exchanger 504 is connected to the compressor 501, and a connection pipe 506 is connected between the other end of the indoor heat exchanger 503 (the end away from the compressor 501) and the other end of the outdoor heat exchanger 504 (the end away from the compressor 501).

The first magnetic element 20 is disposed in the connecting pipe 506, and the variable magnetic field is disposed corresponding to the connecting pipe 506. When the variable magnetic field includes the energized solenoid 10, the energized solenoid 10 is fitted over the outside of the connection pipe 506, and the axis of the energized solenoid 10 extends in the extending direction (axial direction) of the connection pipe 506. When the variable magnetic field includes the second magnetic attraction piece 30 and the third magnetic attraction piece 40, the second magnetic attraction piece 30 and the third magnetic attraction piece 40 are sequentially arranged along the length direction of the connecting pipe 506, the second magnetic attraction piece 30 is located at one end of the connecting pipe 506 in the length direction, and the third magnetic attraction piece 40 is located at the other end of the connecting pipe 506 in the length direction.

The first magnetic attraction piece 20 is arranged in the connecting pipe 506, so that the flow rate of the refrigerant in the connecting pipe 506 can be adjusted, the flow rate of the refrigerant entering the indoor heat exchanger 503 or the outdoor heat exchanger 504 from the connecting pipe 506 can be changed, the amount of the refrigerant entering the indoor heat exchanger 503 or the outdoor heat exchanger 504 from the connecting pipe 506 within a preset time can be changed, and the refrigerating or heating effect can be improved.

Optionally, as shown in fig. 6, the air conditioner further includes a first filter 60 and a second filter 70.

The first filter element 60 is disposed at the other end of the indoor heat exchanger 503 and connected to the connection pipe 506, and is used for preventing the first magnetic attraction element 20 from entering the indoor heat exchanger 503.

The first filter 60 may be a filter mesh or other filter element that is porous.

When the first magnetic attraction piece 20 in the connection pipe 506 flows toward the indoor heat exchanger 503 under the magnetic force of the variable magnetic field, the first filter element 60 can prevent the first magnetic attraction piece 20 from passing through, so as to prevent the first magnetic attraction piece 20 from entering the indoor heat exchanger 503, so that the first magnetic attraction piece 20 can circulate in the connection pipe 506, and prevent the first magnetic attraction piece 20 from entering the indoor heat exchanger 503 to reduce the amount of the first magnetic attraction piece 20 in the connection pipe 506.

The second filter element 70 is disposed at a communication position of the outdoor heat exchanger 504 and the connection pipe 506, and is used for preventing the first magnetic attraction member 20 from entering the outdoor heat exchanger 504.

The second filter 70 may be a filter screen or other filter element that is porous.

When the first magnetic attraction element 20 in the connection pipe 506 flows toward the indoor heat exchanger 503 under the magnetic force of the variable magnetic field, the second filter element 70 can prevent the first magnetic attraction element 20 from passing through, so as to prevent the first magnetic attraction element 20 from entering the outdoor heat exchanger 504, so that the first magnetic attraction element 20 can circulate in the connection pipe 506, and prevent the first magnetic attraction element 20 from entering the outdoor heat exchanger 504 to reduce the amount of the first magnetic attraction element 20 in the connection pipe 506.

Optionally, the air conditioner further comprises a detecting device for detecting the amount on the first magnetically attracted member 20 on the first filter member 60 and/or the second filter member 70. The controller is coupled to the detection device and receives the amount of the first magnetically attracted member 20 on the first filter member 60 and/or the second filter member 70 detected by the detection device.

When the amount of the first magnetic attraction member 20 is greater than the predetermined amount, the controller changes the direction of the current in the energized solenoid 10 until the amount of the first magnetic attraction member 20 is less than or equal to the predetermined amount.

When the accumulation amount of the first magnetic attraction member 20 on the first filter member 60 is greater than the predetermined amount, the controller changes the direction of the current, the direction of the magnetic force received by the first magnetic attraction member 20 changes, and the first magnetic attraction member 20 moves in the opposite direction (toward the second filter member 70), thereby preventing the first magnetic attraction member 20 from being excessively accumulated on the first filter member 60.

Optionally, as shown in fig. 6, the first magnetic attracting element 20 is provided with a through hole 201.

When the first magnetic member 20 is stacked on the refrigerant circulation flow path 50 or the first filter member 60 or the second filter member 70, the refrigerant can continue to flow in the refrigerant circulation flow path 50 through the through hole 201.

Optionally, the number of the through holes 201 on the same first magnetic attraction member 20 is multiple, and the extending directions of at least two through holes 201 in the multiple through holes 201 are different. Thus, when one of the through holes 201 is blocked by the other first magnetic attraction pieces, the cooling medium can flow through the other through holes 201.

Alternatively, the shape of the first magnetic attracting element 20 can be a cuboid shape, a cylindrical shape, and the like.
